Jack, I was in a similar place regarding your H&F statement not long ago.
I have halved my standard drink intake to maybe ~20 a weekend now and I feel SO much better on a daily basis now (probably due to sleeping better on the weekends).
What helped me curb the rampant binge drinking/partying was a renewed focus on software projects I had been meaning to work on, and training for local races (10ks, half marathons).
I am sure you will succeed as you have already identified what you can divert the time and energy to.
My current pre-quarantine schedule was:
Morning 1x long black at a cafe near the office with a colleague
Rest of work day (plus minus 1 on each item) 2x long black from machine in the office, 1-2x long black with another colleague(s) at a cafe
Home (around 5-6pm) 1x long black
Current WFH schedule is: 2-5x long black roughly every 90 mins.
I enjoy the ritual of making it (plunger) and the warmth. I don't think I get a buzz anymore, but the odd time I do, I love it.
I don't get any noticable side effects, and have gone periods 1-4months without drinking it with no adverse effects.
